ART OF PBOJ'ECTIIiE-FIRING;

Specification of Letters Patent. V Patented N 9, 1920 Application filed January 25, 1919. Serial No. 273,201.

To all whom it may concern:

Be it known that I, HENRY CsANYi, a citizen of the'United States, residing at New York, in the county'of New York and State of. New York, have invented new and useful Improvements in the Art of Projectile- Firing, of which the following is-a specification.

. Thisinvention relates to projectile firing operations, pertaining more particularly to ordnance construction and the method of producing the discharging pressures in such operations, the invention being acontinuation in part; of that disclosed in application filed Sept. th, 1916, Ser. No. 121,191. w The present invention is designed to utilize the discharging pressures of combus tible gases, such for instance as the comin various ways, a

ponent gasesof salt or acidulated water, the latter being decomposed lytic' action to produce the gases in a form usable for the purpose. In this manner the combustible gases may be generated in advance of use, admitted to a gas or charge receiving chamber in rearof the projectile and then ignited to produce the discharging pressures." r

The general invention may be carried out simple arrangement being to. provide the breech-block- -movable relative to the barrel, as by hinging-with 'a charge-receiving chamber in rear of the projectile','this chamber being adapted to communicate with a charge-generating chamber which maybe attached to the breech-block or be formed independently of the latter and connected thereto bya suitnected to a. suitable source ply-as. for instance a battery whichisable flexible connection. The charge-gem crating chamber carries the elements of an electrolytic cell, the electrodes being conof electrical supmade op'erative'on the cell at will through a suitableswitch structure, Bymaking the cellactivein the presence of salt water or acidulated water of suitable-character, the decomposition of the water .into its component gases is provided. These being led into the charge-receiving chamber with the breech-block closed,.and the chargeignitedL therein,the projectile will be forced from the barrel.

' The cell may be in open communication with the charge-receiving chamber, but. it as preferred to provide a controllable .port' therebetween. Where the charge is gengases and deliver the charge as needed, thus enabling lncrease 1n the rapldity of firing und r th l ctro' is hereinafter disclosed, said invention con erated for each discharge of a projectile, open communication may be had, the cell being lnactive when firing takes place. It is preferred, however, to close communication at the time offiring, and it is also preferred to provide an arrangement by which the generation is more or less independent'of the firing operations and in such case the structure may be arranged toaccumulate operations.

In either case, howe'ver,the charge is provided by'the electrolytic action and in a separate chamber in order that the charge-receiving' chamber may be maintained free from liquid. f

Tothese and other ends, the nature of which will beunderstoodas the invention sists in theimproved methods and the combinations and constructions hereinafter fullydescribed, illustrated in the accompanylng drawings, and more particularly pointed out in the appended claims. I

In the accompanying drawings, in which similar reference characters indicate similar parts,- i

I Fig. 4 is a View, partly in elevation and partly in section, ofanother form of con-' struction. r Fig. 5 is a view, partly in plan and partly in section of the arrangement of Fig. 4.

Referring to Figs. 1 and 2, 1 indicates the barrelxand 2 the breech-block of an ordnance structure, the breech-block being shown as swingingly associated with the barrel, as at 3, to permit relative movement of the breech-block or barrel as may be preferred, these parts being locked together .in' suitable 'manner when .the gun is being fired. A simple locking arrangement is'by locking bolt 5." 7

..-As shown, the breech-block maybe inthe nature of a magazine having chambers 6 and tending vertically and in spaced parallel.-

- ismthe spacing being dependent on the strength of the current employed one set being in electrical connection with a connector 11 having a binding post connected the explosion servin .jectile, indicated at explosion. I -.j Inrthe form shown in Figsb t to 6, cham-.

totheconductor 12, the otherset being connected electrically with a connector 13, also having a binding post connected to conductor 14. To prevent short-circuiting in cases where the plates have a width to extend over both connectors, platefconnection to the circuit is limited to providing openings in the plate to permit passage of the other connector, the openings being of-sutficient size to provide the insulating effect.- Connector-s11 and 13 are insulated from the breech-block by suitable insulators 16. V V r The electrolyte, which is of a suitable acidulated water form, such for instance as salt water, is placed in rounding the electrode When the; battery cal supply is closed on to the electrode system, the electrolytewill be decomposed into its component gases, thusgeneratiug a comsystem :A therein.

. bustible charge which enters chamber 7 and is more or less compressed therein by the actionof the cell action; This gas may then be ignitedin any suitable manner, as spark plug '17,"

for instance by the use of a to discharge thep roby the. force. of'the ber 7 is shown as connected to the cell by a flexible conne tion 18, said connection leadmg to a suitable plug connection, the outlet being controlled by a suitable valve, indicated as a check valve 20.

In this form the cellis shown as separated from the breech-block, and, as shown inFig.

6, differs from the arrangement of Fig. l in' that provision is made for an accumulation of gases. In this construction, the. electrode system is shown assupported by an. inverted bell 21-the mouth opening downward supportedbn a. tube 22conne :tedto the'casing23, said tube forming. the outlet for the The electrodesystem is of A-are of opposite sign as'in-- 8 may indicate the one connector by 7 chamber 6v thus suror other source of electri? chamber located in valve 19 .to control the igsi l and 2, connectors 11 and 13 being supportedby the bell andbeing connectedto the respective binding posts by conductors 24 and 25. Casing 23 ma-y'have a filling opening 26.

As will be seen, the electrolyte is located both within'and without the bell, the latter serving to isolate the decomposed gases fro the portion of the chamber without the be As the bell is fixed in position, it will be understood that the generation of the gases within the bell produces a pressure therein which tends to drive the liquid outward into the outer chamber portion, thus in turn pro-- ducing a compressionaction on any air that may betrapped therein, the mutual action tending to increase the pressure of the gases of the cell. are introduced into the charge-receiving. chamber under pressure which can be built up bytheaction of the cell, the valve closed, and the charge ignite back pressure on valve 19. a
